Is it a collision, or a pusher tug, there seems to be a rubber fender at the point of the bow.

Hi PD's........ ....have watched this twice  .......they don't appear to be friendly do they  ....Derek

There is a rope to the rear boat, so I guess a rope to the front boat.

Tt looks like a double ended Tow and the rear one wanted to steer the middle one away from the bank.
